Well, I recently had problems with analogy (2.6 release, 4.6 compiler), 
but my problems were with analog sync input. Had too much to do at that 
time to investigate further, so I recompiled my old 2.5.x xenomai with 
-fno-omit-frame-pointer just to get that machine shipped shipped away to 
the physics department to do some quantum dot experiments.
